Manual Linear Stage , X Axis Linear Sliding Platform , Base Plate Sliding Platform
Linear slide rails are generally composed of guide rails, sliders, reversers, rolling bodies and retainers. The steel balls between the guide rails roll instead of direct sliding contact. And the rolling elements can realize infinite circulation in the raceway and the slider with the help of the reverser. It has the advantages of simple structure, small dynamic and static friction coefficient, high positioning accuracy, and good accuracy retention. .
Due to the excellent precision characteristics of linear guides, its application field has begun to expand from traditional industrial equipment. In recent years, linear guides have gradually begun to be used in optical instruments; for example, focusing mechanisms, image movement compensation mechanisms, image plane scanning mechanisms and other mechanisms that require reciprocating linear motion are often used in linear guide pairs.
The manual translation platform consists of a mobile platform and a fixed platform A guide rail or linear bearing is installed to ensure the linear movement between the manual translation table and the fixed table. The selection of guide rail directly affects the performance of the manual translation table.
